I had to speak in front of a big room full of people last week and it was fairly sraight forward and I even had a note card but I havent felt that comfortable in at least a decade or so. I want to be able to do that sort of thing more skillfully but cant think of a way to improve that doesnt involve maximum uncomfortableness or embarassment. Any one here shy or introverted but overcame all that to be able to speak well in front of crowds?
